Investigation of phylogenetic relationships within Saxifraga diversifolia complex (Saxifragaceae) based on restriction-site associated DNA sequence markers.

ABSTRACT: Subsect. Hirculoideae Engl. & Irmsch., belonging to Saxifraga sect. Ciliatae Haw., has high species richness. It can be divided into S. diversifolia, S. pseudohirculus, and S. sinomontana complexes based on morphological characteristics. The species with prominent leaf veins on the posterior leaf edge were placed in the S. diversifolia complex, which is mainly distributed on the eastern and southern margins of the Qinghai-Tibetan Plateau. In this study, 53 samples, representing 15 of the 33 described species in the S. diversifolia complex, were sequenced using the Restriction-site Associated DNA Sequence (RAD-seq) technique. A total of 111,938 high-quality SNP loci were screened to investigate the phylogenetic relationships within the
